AN ADAPTIVE FILTER AND A METHOD OF ADAPTIVE FILTERING

摘要

The present invention relates to an adaptive filter and an adaptive filtering method. The adaptive filter includes an analog filter; an analog-digital converter; a modem; a control part connected to the modem and sensing an adjacent interference signal adjacent to an inner channel signal; and a filter control signal generation part connected to the control part and generating a filter control signal controlling the capacitance of a variable capacitor. A filter pass band adapted for the adjacent interference signal can be controlled. [Reference numerals] (210) Control part; (220) Filter control signal generation part
